Abstract

A single-pass endocardial lead electrode adapted for implantation on or about the heart and for connection to a system for monitoring or stimulating cardiac activity includes a lead body with a circumferential outer surface. The lead includes a first distal end electrode which has a first electrical conducting surface. The lead body also has a second electrode which has a second electrical conducting surface. The second electrode is adapted for positioning and fixation to the wall of the atrium of the heart. A passive fixation element may be used as part of the second electrode. The lead body also includes a curved portion which facilitates the positioning and passive fixation of the second electrode.
